Additional Notes

The 194 bulb is the sole license plate bulb size listed for the Pontiac J2000 Sunbird, covering the 1984-1985 model years.
The 194 is classified as a miniature wedge bulb, designated T10 in the ANSI standard used across the United States and Canada.
The T10 wedge format means the bulb is held in its socket by the tension of the base itself, with no separate metal pins or bayonet fittings involved.
The 194 operates at 12 volts, which is consistent with the standard electrical system voltage found in conventional passenger vehicles of this era.
At 3.78 watts, the 194 draws a relatively low amount of power, a characteristic typical of license plate and courtesy lighting applications.
Because the 194 follows the ANSI standard, it carries a uniform specification recognized by manufacturers across North America, meaning physical and electrical compatibility is governed by that standard rather than by individual manufacturer tolerances.
